Spark Plugs - Electodes falling off!

[Robert Bauer]

Yikes!!!  I changed my plugs tonight on my 93 90q.  The plugs that were in
it were Bosch tri-electrode.  When I pulled cyl. 5 it only had one electrode
on it.  By the looks of it, the other two had been off for a while.  I
didn't have time to do a compression test.  That will have to wait for the
weekend.

Now the questions...Anyone have experience with this?  What are the chances
that they got pushed out the exhaust?  They could be embedded in my pistons
by this point.

I'll be calling Bosch tomorrow.

I'll let you all know what I get on my compression test.

BTW: I put Platinum +4 plugs in.  Any opinions on them?  Other than just
more electrodes to fail and drop into my cylinders!
